OFFICE LAMINATED CUSHIONING SOLE FOR SHOES Arnold Levin, Brooklyn, N. Y.

Application February 9, 1951, Serial No. 210,228 (o1. acs-2s) 1 Claim. 1 Y

This invention relates to laminated cushioning sole for shoes.

This invention relates broadly to a laminated cushioning sole for shoes, lbut includes slippers and shoes of not only the type having full uppers and backs, but uppers of all kinds, closed toe, open toe, closed back, and open back.

More especially therinvention relates to the construction of an improved' cushioning means within the shoe or slipperA which will noti-creep within the shoe Vor form ridges to cause discomfort to the foot of the wearer, especially at the marginal edges of thev inside of the shoe.

Another object of this invention is to provide a cushioned inner slefor a shoe which may bev disposed over the full length of theshoe, or may be positionedeither at .the ball portion or the heel portion of the shoe.

A further object of this invention is to provide in a shoe construction, an insole formed with an upstanding marginal ange or rib within which a portion of a yieldable cushioning member is seated and means is provided whereby distortion of the cushioning membery by pressure of a foot thereon will not cause ridges either transversely or longitudinally of the shoe.

A further object of this invention is to provide a cushioned insole construction which can be used with various types and styles of shoes or footwear.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is a detailed side elevation of a shoe or article of footwear constructed according to an embodiment of this invention,

Figure 2 is a bottom plan view partly broken away of the shoe.

Figure 3 is a fragmentary sectional view taken on ythe line 3--3 of Figure 1.

Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure 1.

Figure 5 is a detailed side elevation of a modified form of this invention.

Figure 6 is a fragmentary longitudinal section o f the shoe shown in Figure 5.

Figure 7 is a detailed side elevation of another modied form of this invention.

Figure 8 is a fragmentary longitudinal section vof the shoe shown in Figure 7.

Referring to the drawings and, rst to Figures 1 to 4, inclusive, the numeral I0 designates generally an outsole, and the numeral I I designates a heel secured to the rear of the outsole. VThe outsole IU has secured to the upper side thereof as by adhesive or other suitable fastening means a laminated cushioned midsole structure generally designated as I2. The laminated cushioned midsole structure I2 includes bottom ply I4 which engages the upper side of the outsole IB, and the upper side ofthe bottom ply I 4 has secured thereto as by adhesive or the like an upstanding margin-ally disposed rib I5. The rib I5 is skived or bevelled as indicated at I6 (see Fig. 4) so as to provide for the substantial merging of the rib structure I5 with the bottom ply I4. A rubber or resilient member I'l is secured by adhesive or other suitable means to the upper side of the bottom ply I4 and projects part way over the upper side of the bevel or skive I6 as shown in Figure 3.

The outer marginal edge of the cushion member I'I which is formed of foam rubber, sponge rubber, or other suitable inherently resilient material terminates inwardly from the upper side of the rib I5 so as to thereby form a space or chamber I8. An upper cushion member I9 is secured as by adhesive or other fastening means to the upper side of the rib or flange member I5 and engages over the upper side of the lower cushion member I1. A fabric member 2l) is adhesively secured to the upper side of the upper cushion member I9 projecting about the marginal edges thereof and engaging over the upper side of the rib or flange I5 as indicated at 2l and then extending downwardly as indicated at 22 about the outer edges of the marginal portions of the rib I5. A leather or other flexible sock lining or insole 23 is adhesively secured over the fabric member 20, and an outer midsole covering strip 24 is secured by stitching or other fastening means 25 to the marginal edges of the sock lining 23. The shoe includes a vamp 21 which is interposed between the downturned marginal portions of the sock lining 23 and midsole covering strip 24 so as to be secured thereto by the stitching 25.

The midsole cover 24 is formed with a lower inwardly projecting extension 28 which engages between the outsole I0 and the bottom ply I4 of the cushioned midsole. The extension 28 is adhesively secured between the outsole member I Il and the bottomiply l. The shoe construction shown in Figures 1 to 4, inclusive, contemplates the provisionrofa cushioning midjsole construction over the entire upper side of the outsole member I and including the shank and heel portion of the shoe.

Referring now to Figures 5 and 6 there is disclosed a modied form of this construction wherein the cushioned midsole construction I2a which is identical with the cushioned midsole construction I2 with the exception that the cushioned structure I2a extends throughout the forepart of the toe portion forward of the shank portion of the shoe.

Referring now to Figures 7 and 8 there is disclosed another modification of this invention wherein the cushioned midsole structure I 2b is identical with the cushioned midsole construction I2 with the exception that the insole structure I2b extends from the ball line of the shoe over the heel portion.

The cushioned insole construction hereinbefore described will provide a resilient cushioning means which will cushion the foot in the shoe and will provide for4 eliminating the ridges which have heretofore been formed in cushioned insoles in prior use. The provision of the chamber I8 between the outer portions of the two cushioned members I1 and I9 provides a means whereby either onev or both of the cushioned members I'I and I9 may be distorted outwardly into the chamber I8 without causing any outward appearance of distortion about the marginal portions of the bottom portion construction. The cushioned midsole construction is herein disclosed as being combined with an outsole having a heel secured thereto, but it will be understood that this cushioned midsole construction may be used With various types of shoes which may or may not have heels. When made of the desirable height as can readily be done by suitable planning of dimensions,

the cushion midsole as referred to herein may also be a platform or platform type of shoe or slipper. It will be understood, therefore, that as used herein the term cushion midsole also comprehends a "platform as such designation is understood in the trade.

What is claimed is:

A laminated cushioned midsole assembly corn- 4 prising a bottom ply, a marginal upstanding rib secured to the upper side of said bottom ply, said marginal rib being beveled on the inner edge, cushioning means disposed within the area defined by said rib and engaging only the lower part of the upper side of the bevel edge of said rib, a second cushioning ply overlies thei'lrst cushioning means and engages the top of the rib, a fabric member secured to the upper side of said second cushioning ply, the marginalfedges of said fabric cover member extending downwardly over the outer edge of said rib and secured thereto.
